 Unlike Western Christian architecture with its tendencies of modernity (see, e.g., Liverpool Metropolitan Cathedral or Notre Dame du Haut), Orthodox architectural style remains largely conservative and traditional.One notable and architecturally important exception is Frank Lloyd Wright's design of Annunciation Greek Orthodox Church in Wauwatosa, Wisconsin, in the United States.The Archdiocesan Cathedral of the Holy Trinity on New York City's Upper East Side is the largest Orthodox Christian church in the Western Hemisphere.
